Displaying the current temperature:
The thermostat will display the current temperature in°C by default. When in any other mode making no input for approximately 5 seconds will cause the thermostat to return to this default display.
 
Setting the trigger temperature:
To set the trigger temperature press the button marked'SET'. The seven segment display will flash. You can now set a trigger temperature(in°C) using the'+' and'-' buttons in 0.1 degree increments. If no buttons are pressed for approximately 2 seconds the trigger temperature will be stored and the display will return back to the current temperature.

Setting the parameters:
To set any parameter long press the'SET' button for at least 5 seconds. The seven segment display should now display'P0'. This represents parameter P0. Pressing the'+' or'-' buttons will cycle though the various parameters(P0 to P6). Pressing the'SET' button whilst any of there parameters are displayed will allow you to change the value for that parameter using the'+' and'-' buttons(see below). When finished setting a parameter press the set button to exit that option. If no buttons are pressed for approximately 5 seconds the thermostat will exit the parameter options and will return back to the default temperature display.

Setting the cooling or heating parameter P0:
The parameter P0 has two settings, C and H. When set to C(default) the relay will energise when the temperature is reached. Use this setting if connecting to an air-conditioning. When set to H the relay will de-energise when the temperature is reached. Use this setting if controlling a heating device.

Setting the hysteresis parameter P1:
This sets how much change in temperature must occur before the relay will change state. For example if set to the default 2°C and the the trigger temperature has been set to 25°C, it will not deenergise until the temperature falls back below below 23°C. Setting this hysteresis helps stop the thermostat from continually triggering when the temperature drifts around the trip temperature.

Setting the upper limit of the thermostat parameter P2:
This parameter limits the maximum trigger temperature that can be set. It can be used as a safe to stop an excessively high trigger temperature from accidentally being set by the user.

Setting the lower limit of the thermostat parameter P3:
This parameter limits the minimum trigger temperature that can be set. It can be used as a safe to stop an excessively low trigger temperature from accidentally being set by the user.

Setting temperature offset correction parameter P4:
Should you find there is a difference between the displayed temperature and the actual temperature(for instance if the temperature probe is on a long run of cable) you can make corrections to the temperature reading with this parameter.

Setting the trigger delay parameter P5:
This parameter allows for delaying switching of the relay when the trigger temperature has be reached. The parameter can be set in  minute increments up to a maximum of 10 minutes.

Setting the high temperature alarm parameter P6: Setting a value for this parameter will cause the relay to switch off when the the temperature reaches this setting. The seven segment display will also show'---' to indicate an alarm condition. The relay will not re-energise until the temperature falls below this value. The default setting is OFF.

Instructions for use:
Connect the power supply and equipment, the measuring temperature is displayed, press the"SET" button, press"+ or-" to set the desired temperature(long press"+ or-" to quickly increase or decrease), press"SET" to confirm the setting and return.

The controller automatically performs the relay ON/OFF. The relay output is 20A, meet a variety of high-power loads,
LED status Indicator: LED off indicates the relay open; LED on indicates the relay is closed.
Digital LED display:"LL" indicates sensor is open,"HH" indicates over range, the relay will be forcibly disconnected;"---" indicates high temperature alarm
Long press the"SET" button to enter the main menu settings, press"+ or-" to switch between P0-P6, then long press"SET" or 10 seconds without keystrokes to confirm the setting and return.
